The ASTM D1623-2017 standard specifies a test method for determining the tensile strength and tensile adhesion of rigid foam plastics. The standard aims to evaluate the tensile strength and adhesion to the substrate by testing the tensile performance of rigid foam samples. These properties are essential for the application of foam plastics in construction, automotive, Encasement and other industries, as they directly affect the durability and Reliability of foam materials. The standard describes in detail the specimen prepative, test conditions, equipment requirements and data processing methods to ensure the accuracy and repeatability of test results. Through this test method, manufacturers can optimize the production process of foam plastics, improve the product mass and ensure its performance in actual use.
